Whoever you choose, just make sure they are affiliated with either SwedishAmerican or Rockford Memorial Hospital. St. Anthony's Medical Center is great for adult care, but they have a terrible pediatrics care floor if your child ever needs in patient care. The second choice is Swedish American--they at least have a Pediatrics floor, though they do NOT have Pediatric Intensive Care. For that, only Rockford Memorial has a PICU. So if your child has any unusual health conditions, you would really be wise to find a pediatrician affiliated with Rockford Health System, though I personally don't have any preference for them, and in fact drive my kids to doctors in Madison, WI. I just wanted you to know what the hospital care is like in Rockford, as some people don't think about that when choosing a doctor, and if you need it later, it can be a BIG hassle. Best of luck, K.
P.S. My sister uses a pediatrician in the group at Rockford Clinic and seems happy with him.
